For the gun, the hit probability is a function of many error budgets. A selected design parameter among error budgets is assumed to be a vertical gun jump. The hit probability depends on the vertical gun jump for a given range. To satisfy a given hit probability for the given range, the vertical gun jump should be confined into the interval. At first, to obtain a vertical variance at the target, the unit partial is determined using the trajectory. The unit partial means the difference between two vertical displacements at a given range under two fire angles whose difference is the unit quantity. Using the unit partial and the variance of the vertical gun jump, we may determine the hit probability using the Polya-Williams’ formula. Finally, we may obtain the allowable interval for a given jump within which the given hit probability is satisfied.
